The Omega Speedmaster Professional is by far one of our most favorite chronographs. The Speedmaster has an incredible history starting with automotive racing moving into flight and eventually to NASA and the U.S. Space Program.  There are many subtle differences within the vintage Omega Speedmaster range of references that make them all slightly unique and different.

This Omega Speedmaster transitional model Ref. 145.012 dates this specific example too late 1968 uses the earlier Caliber 321 movement. The original matte black stepped dial with applied Omega logo has achieved a wonderful patina and the bezel insert has the original dot over 90 (DON) bezel, and pre-moon seahorse case back. This specific example is a very rare last production pre-moon reference. 

 

The step dial or "Pie Pan" Omega Speedmaster's possess a charm and feel that that the new modern equivalents don't seem to quite have. The Ref 145.012 with the workhorse Cal. 321 movement is clearly built to last. The Speedmaster looks great on the bracelet as well as a handcrafted leather strap. It is one of our favorite chronographs due to its timeless design and functionality. Its versatility to be paired with the most formal and the most casual of wardrobe also makes the Speedmaster a good choice for the first vintage timepiece and or a classic daily driver.

The case is believed to remain in unpolished condition with original factory finishes and sharp lugs, showing honest wear from use. The original "Dot over 90" (DON) bezel insert is in excellent condition and remains deep black in coloration. The crown is an early service replacement. The "Pre-Moon" Seahorse case back has very minimal wear and is clearly visible. The era correct Omega 1039 flat-link stretch bracelet with 516 end pieces remains in excellent unpolished condition showing little wear and very light stretch from use.

DIAL & HANDS

The matte black "step" dial with applied Omega logo is in wonderful vintage condition. The original tritium markers have taken on a nice ivory patina, under U.V. light inspection the 3 o'clock marker show some degradation above the step, all the other markers remain fully intact. The original tritium hands have aged a shade darker than the dial, which is common for Speedmasters and exhibit no degradation under U.V. light inspection.
